Application filed February 8, 1915. Serial No. 6,942.

To allwhom it may concern:

Be it known that I, CHARLES F. KARBERG, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Awning-Operating Mechanism, of which the following is a specification.

This invention pertains to an improvement in awning operating mehanism as compared, especially, with Letters Patent of the United States issued to I. J. Daniels, and bearing Nos. 546,730, of Sept. 24, 1895, and 784,475, of May 7, 1905, respectively and owned by The Cleveland-Akron Bag- Company, the assignees of this invention. The improvement consists in the material differences in the construction and combination of parts as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a rear elevation of the casing and parts therein as seen frornthe. left in Fig. 2, and Fig. 2 is a vertical sectional elevation front to rear of the complete device in worklng condition. Sheet 2 of the drawings contains sundry details of the parts. Thus, Fig. 3 is a perspective View of the shaft coupling. Fig. 4 is a perspective view of the pivotally mounted detent or dog which looks the parts against unwinding. Fig. 5 is a perspective view of the rod that supports said detent. Figs. 6 and 7 are perspective views of the two operating-gears, and Figs. 8 and 9 are perspectives of the two sections of thecasing.

As thus shown, the first essential improvement over the two patents above referred to is found in the inclosing casing. In the said patents the casing or housing for the operating partsconsists in a box cast in a single piece within which the operating parts are mounted and the only openmg or entrance to the parts for approach or removal is at the rear, which is closed by bolting the box to its support. Hence, the gears and all the other contained parts are effectually locked in and cannot be reached without bodily detaching the box with all its heavy contents. Experience has demonstrated that this is an inefiicient device and inconvenient in use as well as being otherwise objectionable, as when a spring or other part becomes displaced or unserviceable and has to be fixed or replaced. The said casing is also otherwise improved by the present changeas will presently appear. Thus, the caslng 1s constructed'in two parts or sections a and 0, front and rear, respectively. The rear or inner section which is also the main sectlon, is provided with a diaphragm or wall to across its front which extends about half way up and is featured with two journal bearings b and b at right angles to each other and, an opening Z2 about its middle to support a rod. Above said wall the front of the said section is open to provide a working space for the horizontally disposed bevel or miter gear 9', the actuating gear in mesh therewith being positioned at the front of said wall within the section 0 of the casing. Practically, the two gears and all the other working parts are mounted in or upon the said wall plus the two hearings in the casing itself. Thus, the initial or actuating gear 9 has a tapered tubular spindle 2 which occupies the correspondngly shaped bearing 7) in said wall and at its front in th e section 0, while the gear 9 is supported over or upon said diaphragm by the shaft coupling member on, which has an angular shank 3 on which the said gear is engaged and a cylindrical extremity 4 beneath said gear. adapted to rotate in the bearing 6. A dividedibearing 6 having one 'half in the top of each of the two casing sections, is formed in line with the bearing 5 and serves as a further support for the coupling member an and releases said member for removal when the front section 0 is detached. The said member is provided with a yoke 5 at its top adapted to attach :an operating shaft thereto, and said member is driven by. and through the gear 9.

The gear 9. is removably mounted on the :square shank 6 of the shaft n, which shank is of such length in the said gear that the shaft can be moved back and forth axially within all operating requirements and still hold its working relations with the said gear. The inner portion of said shaft is formed with a stem which is slidable in the tubular extension 2 of the gear 9 within limits, or as much as may be required to operate the detent or dog (Z. The operat ing or crank handle it is mounted in a sleeve or head ft on the outer end of the said shaft and serves to both rotate the shaft and the gear thereon and to slide the shaft back and forth according to the position desired at a given time for the control of the detent (Z.

The said detent is hung in its own side bearings 8 on a transverse rod 9 fixed at its ends in the rear middle portion of the main casing section 0, and is further provided with a tooth 10 on its inside and top and an arm 12 at its bottom provided with a hole near its end in registering relations with the spring supporting rod 14, supported at its inner end in the hole 6 in the said diaphragm and in which the said rod is fixed fluid tight. A spiral spring 15 is mounted on said rod between said arm and the said wall and serves to normally press outward on the arm 12 and keep the dog or detent (Z in locking engagement with the gear 9. To this end the said gear has a hub provided with a series of pockets or recesses 16 at intervals about its top, four in this instance, and adapted to be engaged by the tooth 10 when the said dog is in normal position. That is, when the awning is wound up and the shaft n withdrawn a suitable distance to release said dog, it will be instantly forced into engaging position by the spring 15 and will remain there until purposely released by thrusting said shaft inward, say to the extent shown in Fig. 2, and throwing the dog or detent back out of engagement. It will be seen in Fig. 4, especially, that said dog has a hump or lug 18 at the base of arm 12 relatively between the pivot bearings 8 and provided with a beveled or more or less rounded under surface adapted to be engaged by the said shaft n and whereby the dog is forcibly swung back at its top and inward at its bottom when the stem .9 is thrust inward until the gear 9 is released. At this time the operator has hold of the crank or handle 71. and is in control of the mechanism so that he can raise or lower the awning at pleasure.

It is to be especially noticed by the foregoing construction, that the dog is held back out of locking position as long as the shaft a is projected inward, as seen in Fig. 2, an opening in the dog affording room for the said shaft at the base of said hump, and the detent is thus locked against the tension of its spring and cannot swing back to engaging position until the said stem is purposely withdrawn. This remedies the serious former defect of having the dog constantly free to swing to locking position under heavy spring pressure as formerly and compelling the operator to exert a constant inward pressure to overcome the tension of the spring. In the present construction, the shaft it looks the dog back out of engagement until it is purposely released, and the spring operates simply against the dog and never against the shaft; This contributes Copies of this patent may be obtained for very materially to the easy operation of the awning as compared with the former construction.

The handle or crank it is detachably secured to the end of shaft 71 by a set screw 19 through the integral looph on the end of the shaft. Of course, the said shaft can be bodily withdrawn at any time and removed with the handle, and the front casing section can then be detached without dis turbing any of the operating parts but which also will be exposed for removal, one or all, as may be needed. In fact, all the parts can be separately removed from the front of the casing, when duly released and the opening over the diaphragm or wall to affords access to the dog (Z and the spring at the rear. The said wall also provides a lubricating pocket or chamber in the front of the casing in which the gear 9' is slightly immersed and which carries the lubricant to other parts.

hat I claim is:

1. A casing as described consisting of front and rear sections, the rear section having a vertically disposed integral wall substantially half its depth at its inside and provided with journal bearings at right angles to each other, a transmitting gear having a journal mounted in one of said bearings and an actuating gear having a tubular spindle mounted in the other bearing, in combination with a pivoted detent having a projection on its inside and provided with a hump adapted to engage said transmitting gear, and a shaft projected through said actuating gear and the spindle thereof and adapted to contact with said projection and release said detent.

2. A device of the class described, comprising an inclosing casing and a transmitting gear and an actuating gear in mesh at right angles with each other in said casing, in combination with a detent of substantially T shape, a rod extending transversely through said casing and having the detent pivoted thereon said detent being provided with a tooth adapted to engage the trans mitting gear and with a projection near its middle and front, and a shaft in rotating relation with said actuating gear and having a stem projected through the axis thereof into contact with said projection on said detent and adapted to throw and hold the detent back out of engagement with said transmitting gear.

In testimony whereof I afiix my signature in presence of two witnesses.
